Systems and methods for identifying virtual communication platform users

ABSTRACT

Methods for handling traffic between a first network including a virtual communication platform and a second network, such as a circuit-switched network, include inserting customer identifiers into data packets. For traffic sent to the second network, the packets with the identifiers are transmitted to a trunking service that uses the identifier to determine one or more applicable service attributes for handling the data contained within the packets. For data traffic received from the second network, the virtual communication platform uses the identifiers to determine a destination, such as an endpoint device, for the traffic within the first network.

TECHNICAL FIELD

Aspects of the present disclosure involve managing call traffic when the originator of the call may not be known or readily discernible. More specifically, aspects of the present disclosure involve managing traffic between virtual communication platforms, such as cloud-based private branch exchanges, and other networks including public switched telephone networks.

BACKGROUND

A private branch exchange (PBX) is a private telephone exchange or switching system that may be implemented within an enterprise. The PBX enables internal phone calls to be routed within the PBX while routing external phone calls to a reduced set of external lines, thereby reducing telephony costs for the enterprise. PBX systems also enable customization of the internal phone network to best suit the needs of the enterprise such as by modifying the PBX with one or more modules that provide additional telephony functionality such as voicemail, conference calling, call waiting, and the like.

Many PBX systems communicate using internet protocol (IP) and session initiation protocol (SIP). As a result, such PBX systems typically require gateways or similar equipment to facilitate communication between the internal IP-based network of the enterprise and legacy telephone networks, such as the public switched telephone network (PSTN). Through a process referred to as “trunking”, traffic to and from lines of the PBX are consolidated onto a virtual connection, which may be over the Internet or a virtual private network (VPN), and communicated between a trunking service provider and the PBX system. Accordingly, externally directed traffic originating from endpoint client devices of a PBX system is consolidated onto the virtual connection and transmitted to the trunking service provider, which then performs the necessary conversion of the IP-based traffic to signals compatible with the PSTN. Similarly, the trunking service provider converts signals from the PSTN into IP-based traffic and consolidates the IP-based traffic onto the virtual connection for transmission to the PBX system. The PBX system then routes the traffic as necessary to one or more endpoint client devices.

It is with these observations in mind, among others, that aspects of the present disclosure were conceived.

DETAILED DESCRIPTION

Many conventional PBX systems require enterprises to deploy one or more PBX servers, which use a broadband modem to connect to a session border controller, gateway, or other network equipment of a trunking service. However, in light of the costs and general inefficiency of enterprises maintaining their own PBX systems, much functionality of traditional PBX systems is available over the Internet through third-party providers. Such virtual communication platforms may include telephony functionality of PBX systems, as well as broader functionality of unified communications and collaboration platforms including, without limitation, instant messaging, presence information, voice, video, mobility features, conferencing, desktop sharing, and the like.

In such virtual PBX platforms, a host system communicates with endpoint client devices of a customer enterprise over the Internet or a virtual private network (VPN). Similar to conventional PBX systems, traffic within an enterprise is handled primarily by the virtual communication platform, which makes connections, routes traffic, and otherwise facilitates communication between endpoint client devices. However, communication outside of the enterprise and, in particular communication that requires use of the public switched telephone network (PSTN) or similar networks, still requires the use of a trunk between the host system of the virtual communication platform and a trunking service provider to consolidate and transmit IP-based data to the trunking service provider. The trunking service provider may then convert the IP-based traffic into a signal or format suitable for communication over the PSTN or other network. A similar process operates in reverse for traffic received by the trunking service provider over the PSTN and intended for a network device of the virtual PBX system.

Many PBX servers are connected directly to trunking service providers and with each PBX server being readily identifiable by a public IP address or a combination of a VPN identifier and private network address within the VPN. Identification of the customer enterprise from which traffic originates is useful in ensuring that the traffic is handled by the trunking service provider appropriately and often according to a service contract between the customer enterprise and the trunking service provider. Such contracts may dictate the number of lines available to a customer enterprise, billing terms, quality of service (QoS) requirements, and other attributes of the trunking service. Moreover, being able to identify and monitor the source of particular traffic enables trunking service providers to evaluate the health and performance of their networks and to inform maintenance, capital improvement, and other strategic business decisions.

Virtual communication platforms, such as cloud-based PBX platforms, typically preclude the use of an IP address to identify a customer enterprise. Specifically, the trunking service provider equipment is generally only aware of the IP address of the virtual communication platform from which the network elements of the trunk provider receive the traffic. Because virtual communication platforms may handle traffic from multiple customer enterprises of the trunking service provider, the IP address of the virtual communication platform does not reliably indicate the originating source of particular traffic. Stated differently, it can be challenging to identify the customer originating the traffic and to subsequently manage the traffic on a customer basis.

In light of the foregoing challenges, among others, systems and methods disclosed herein use customer identifiers to identify the customer enterprise associated with traffic handled by the trunking service provider. More specifically, customer identifiers are inserted into headers of session initiation protocol (SIP) or similar messages passed between the virtual communication platform and the trunking service provider. The customer identifier may then be used to perform a lookup and identify the specific customer enterprise associated with the message and corresponding traffic.

Although described below in more detail, systems and methods for handling traffic originating at an endpoint client device and then directed to a PSTN or other telecommunication platform include the endpoint device generating a packet and transmitting the packet to a network element, such as a session border controller, of a virtual communication platform. In one example, the virtual communication platform is a cloud-based PBX. In response to receiving the packet, the virtual communication platform retrieves a unique identifier associated with the endpoint client device or more generally the customer associated with the endpoint device, inserts the unique identifier into a header of the packet, which may be a SIP message, and forwards the packet to a session border controller or other network element of a trunking service provider. The network element of the trunking service provider then extracts the identifier from the header and then identifies the customer enterprise associated with the customer identifier and one or more attributes of a service provided by the trunking service provider to the customer enterprise. The network element of the trunking service provider then routes the traffic (or signals derived therefrom) over the PSTN or other telecommunication platform in accordance with the service attributes.

In the specific example of connecting with a PSTN, when receiving traffic from the PSTN that is destined for an endpoint client device of a customer enterprise, a signal is received by a network element of the trunking service provider from a telephony device of the PSTN. The signal generally includes or is preceded by a signal including a destination identifier, such as a phone number. The network element of the trunking service provider uses the destination identifier to perform a lookup and retrieve an identifier corresponding to the customer enterprise associated with the endpoint client device. The network element of the trunking service provider then generates a packet based on the received signal, inserts the identifier into the header of the packet, and transmits the packet to a network element of a virtual communication platform. The network element of the virtual communication platform may then extract the identifier, perform a lookup using the identifier to determine an address of the endpoint client device, and forward the packet to the endpoint client device according to the address.

For purposes of this disclosure, virtual PBX services, unified communications and collaboration services, and similar services are may be referred to generally as communications services. Accordingly, a virtual communication platform in the context of the present disclosure may host multiple communication services for use by respective enterprises, individuals, or other users. Although the present disclosure uses virtual PBX and unified communications and collaboration services as primary examples of communication services for which the present disclosure is applicable, the principles and concepts disclosed herein may be readily adapted to provide other virtualized communication services.

FIG. 1 is a schematic illustration of an example network environment 100 for processing telephone calls. In one implementation, each of a first customer network 102 and a second customer network 104 are connected to a virtual communication platform 106. The virtual communication platform 106 may include one or more network elements such as a session border controller, a gateway, a router or switch, and a server. Accordingly, reference to the virtual communication platform 106 should be understood to refer either to the virtual communication platform 106 as a whole or to one or more network elements contained within the virtual communication platform 106.

The first customer network 102 may include a plurality of first endpoint client devices or user agents, such as client endpoints devices 112-118, connected to the virtual communication platform 106 through a first customer network edge device 128. The first customer network edge device 128 is generally in communication with a first border function 132. Similarly, the second customer network may include a plurality of second endpoint client devices or user agents, such as client endpoint devices 120-126, connected to the virtual communication platform 106 through a second customer network edge device 130 and the first border function 132. The endpoint client devices 112-126 may include any telephony or computing devices capable of creating and receiving packets. For example, in certain implementations, each of the endpoint client devices 112-126 are a session initiation protocol (SIP)-enabled devices and may include, without limitation, one or more of a desktop telephone, a smartphone, a laptop computer, a desktop computer, and a tablet. The first border function 132 may include, without limitation, one or more of a modem, a session border controller, a gateway, or a similar device including hardware and software adapted to process traffic to and from the first and second customer networks 102, 104. The first border function 132 may further include functionality for encrypting and decrypting traffic handled by the first border function 132 and performing authentication of devices transmitting traffic to or receiving traffic from the first border function 132.

The virtual communication platform 106 may be connected to a trunking service provider 108 over a trunk 110, which may be a SIP trunk. The trunking service provider 108 may include one or more network elements such as, without limitation, one or more of a session border controller, a gateway, a router or switch, and a server. Accordingly, reference to the trunking service provider 108 should be understood to refer either to the trunking service provider 108 as a whole or to one or more network element contained within the trunking service provider 108. The trunk 110 is a virtual connection that may be established over the Internet or similar network and over which traffic between the virtual communication platform 106 and the trunking service provider 108 is consolidated. In certain implementations, the trunk 110 may extend between a border function 134 of the virtual communication platform 106 and a border function 136 of the trunking service provider. Similar to the border function 132, each of the border functions 134 and 136 may include, without limitation, one or more of a modem, a session border controller, a gateway, or similar devices including hardware or software adapted to process traffic between the virtual communication platform 106 and the trunking service provider 108. The trunking service provider 108 is further connected to a public switched telephone network (PSTN) 112 through another border function 138.

During operation, the virtual communication platform 106 receives packets from the endpoint client devices 112-126 corresponding to communications to be delivered over the PSTN 150. For example, the endpoint client devices 112-126 may be voice over Internet protocol (VoIP) devices and the packets transmitted to and from the endpoint client devices 112-126 may include encoded voice information related to a call between one or more of the endpoint client devices 112-126 and one or more telephone devices connected to the PSTN 150. The virtual communication platform 106 then transmits the packets to the trunking service provider 108 over the trunk 110. For example, when initiating a call or similar communication, one of the endpoint client devices 112-126 may generate a SIP request message and transmit the SIP request message to the virtual communication platform 106. In response to receiving a packet from one of the client devices 112-126, the virtual communication platform 106 performs a lookup using data contained within the packet to determine a unique identifier assigned to the customer enterprise to which the endpoint client device belongs. For example, in certain implementations, the virtual communication platform 106 may extract a source IP address from the packet and perform a lookup in a customer identifier database 140 that correlates IP addresses with customer identifiers. The lookup may also be performed using other identifying information such as including, without limitation, a VPN identifier and private network address. The virtual communication platform 106 then inserts the customer identifier into a header of the packet and transmits the packet to the trunking service provider 108 over the trunk 110.

The customer identifier may be in any form suitable for insertion into a packet provided it may be used to uniquely identify a particular customer enterprise. In certain implementations, the customer identifier may adhere to one or more standards. For example, the customer identifier may correspond to a trunk group identifier as published by the Internet Engineering Task Force (IETF®) in Request for Comment (RFC) 4904. In other implementations, the customer identifier may be inserted into standard fields of a packet. For example, in the context of SIP signaling, the outgoing trunk group (OTG), destination trunk group (DTG), or TRGP fields may be used to store the customer identifier. In still other implementations, domain name server (DNS) entries corresponding to separate IP addresses may be used as customer identifiers.

When the trunking service provider 108 receives a packet including a customer identifier, the trunking service provider 108 extracts the customer identifier from the packet header and performs a lookup to identify the corresponding customer enterprise and, more specifically, to identify attributes of services provided to the customer enterprise. For example, in certain implementations, the trunking service provider 108 may query the customer identifier database 140 to receive a name or other identifier of the customer enterprise that is then used to query a service database 142 that includes attributes of services provided by the trunking service provider 108 to customer enterprises. Alternatively, the service profile database 142 may include customer identifiers and may be queried directly by the trunking service provider 108.

After obtaining the relevant service attributes, the packet is processed in accordance with the service attributes by the trunking service provider 108. In general, the trunking service provider 108 will convert the packet to a signal compatible with a telecommunications network and transmit the signal to the appropriate destination. For example, if the trunking service provider 108 facilitates communication with the PSTN 150, the trunking service provider 108 may convert packets received form the virtual communication platform 106 into a PSTN-compatible signal, such as a signaling system number 7 (SS7) signal. In addition to signal transmission over the PSTN, the trunking service provider 108 may perform additional functions based on the service attributes. For example, the trunking service provider 108 may perform various functions specific to the customer enterprise and related to the terms of service as represented by the service attributes. Such functions may include, without limitation, one or more of billing functions, line usage tracking, bandwidth tracking, and quality of service (QoS) analysis.

For traffic originating from the PSTN 150, the trunking service provider 108 receives a signal destined for one of the endpoint client devices 112-126 or, in the case of a conference call or similar function, the virtual communication platform 106. Signals received from the PSTN 150 may include or may be preceded by one or more signals including a destination identifier, such as a phone number. In certain implementations, the trunking service provider 108 performs a lookup using the destination identifier to determine the customer identifier associated with the destination of the traffic from the PSTN 150. For example, the customer identifier database 140 may further include entries in which destination identifiers are correlated with corresponding customer identifiers such that the customer identifier may be obtained by performing a lookup using the destination identifier. The trunking service provider 108 may then generate a packet corresponding to the received signal and insert the customer identifier into a header of the packet before transmitting the packet to the virtual communication platform 106.

FIGS. 2A and 2B further illustrate transfer of traffic originating from a customer network, such as the customer networks 102, 104 of FIG. 1, and intended for delivery over a circuit-switched network, such as the PSTN 150, or other network. More specifically, FIG. 2A is a schematic illustration 200 of traffic sent from a customer network and being forwarded by the virtual communication platform 106 to the trunking service 108. FIG. 2B is a second schematic illustration 250 depicting the subsequent operations carried out by the trunking service 108 to deliver the data received from the virtual communication platform 106 to the PSTN 150 or similar network. The processes illustrated in FIGS. 2A and 2B are also represented in FIGS. 3A and 3B, which are flow charts illustrating corresponding methods 300 and 350.

Reference is first made to FIGS. 1, 2A, and 3A to describe the process of handling traffic from a customer network, which is further illustrated by the method 300 of FIG. 3A. The process of handling traffic from a customer network, such as the customer network 102, begins at operation 302 with the virtual communication platform 106 receiving data from the customer network 102. For example, in certain implementations, the data received by the virtual communication platform may be in the form of a packet including voice or other communications data. The packet may further include one or more attributes or identifiers associated with the customer of the customer network 102. For example, in certain implementations, the packet may include, among other things, an Internet protocol (IP) address, an identifier associated with the customer network 102, or an identifier associated with one or more network elements of the customer network 102.

At operation 304, the virtual communication platform 106 performs a lookup or similar operation using the attribute of the packet to determine a customer identifier associated with the attribute. For example, in some implementations, the virtual communication platform 106 may be communicatively coupled to a customer data source 160 containing one or more tables or similar data structures that correlate attributes within packets to particular customers of the virtual communication platform and corresponding trunking services. One example of an attribute may be a public IP address. Another example of an attribute may be a combination of a VPN identifier and a private IP address.

At operation 306, the virtual communication platform 106 generates a second packet including the customer identifier determined in operation 304. Generating the second packet may include simply inserting the customer identifier into the packet received during operation 302 or may include generating an entirely new packet including the customer identifier. In certain implementations, the customer identifier is inserted by the virtual communication platform 106 into a header of the second packet.

At operation 308, the virtual communication platform 106 transmits the second packet to the trunking service 108.

Reference is next made to FIGS. 2B and 3B, the latter of which is a flow chart illustrating a method 350 for handling traffic received from the virtual communication platform 106 by the trunking service 108. At operation 352, the trunking service 108 receives a packet, such as the second packet described above in the context of FIGS. 2A and 3A, from the virtual communication platform 106. As previously discussed, such packets include data received from a customer network 102 as well as a customer identifier inserted into the packet by the virtual communication platform 106.

At operation 354, the trunking service 108 performs a lookup or similar operation using the customer identifier included in the packet to identify one or more service attributes. The service attributes are used by the trunking service 108 to determine parameters for how the traffic received from the virtual communication platform 106 is to be recorded, tracked, or otherwise handled. For example, in certain instances, a customer's voice services may be governed by each of a first services agreement with an operator of the virtual communication platform 106 and a second services agreement with an operator of the trunking service 108 and associated network. Accordingly, while the virtual communication platform 106 may handle voicemail, conference calling, or similar functions, traffic is ultimately handled by the network operator and governed by the agreement with between the customer and the network operator. Accordingly, data received from the customer and handled by the network operator, such as data received at the trunking service 108, must often be tracked or be subject to other terms of service. To facilitate such data handling, the service attribute may be used to, among other things, determine the particular parameters governing data handled by the network operator and to track data handled by the network operator. For example, the service attributes may corresponding to, but are not limited to, billing functions, line usage tracking functions, and quality of service functions. To facilitate identifying service attributes, the trunking service 108 may be communicatively coupled to a data source 170 that correlates a customer's customer identifier with service attributes for one or more services provided to the customer.

At operation 356, the trunking service 108 converts the packet to a format suitable for transmission over a second network. For example, in certain implementations, the trunking service 108 converts the data included in the packet to a format suitable for transmission over a circuit-switched network, such as the PSTN 150, or other network. At operation 508, the trunking service 108 transmits the converted data over the network in accordance with the service attribute.

FIGS. 4A and 4B further illustrate transfer of traffic originating from a circuit-switched or other network, such as the PSTN 150 of FIG. 1, and intended for delivery to an endpoint device of a customer network, such as one of the endpoint devices 112-118 of the first customer networks 102 or the endpoint devices 120-126 of the second customer network 104. More specifically, FIG. 4A is a schematic illustration 400 of traffic sent from the PSTN 150 and being forwarded by the trunking service 108 to the virtual communication platform 106. FIG. 4B is a second schematic illustration 450 depicting the subsequent operations carried out by the virtual communication platform 106 to deliver the data received from the trunking service 106 to one of the customer networks 102, 104. The processes illustrated in FIGS. 4A and 4B are also represented in FIGS. 5A and 5B, which are flow charts illustrating corresponding methods 500 and 550.

Reference is next made to FIGS. 1, 4A, and 5A to describe the process of handling traffic received from the PSTN 150 or similar network by the trunking service 108. The process of handling such traffic begins at operation 502 with the trunking service 106 receiving a telecommunications or other signal from the PSTN 150. In general, such traffic includes a destination identifier, such as a phone number, corresponding to an intended destination of the traffic.

At operation 504, the trunking service 108 performs a lookup or similar operation using the destination identifier to determine a customer-related identifier associated with the intended destination of the received signal. For example, in certain implementations the customer-related identifier may be a unique identifier associated with one of the customer networks 102, 104 or, in certain implementations, one of the client devices 112-118, 120-126. In certain implementations, the customer-related identifier may be a combination of an identifier obtained by performing a lookup operation and data derived from the signal. For example, the customer-related identifier may be a combination of a customer network identifier and the destination identifier received as part of the signal.

At operation 506, the trunking service 108 generates a packet including data corresponding to the received signal and inserts the identifier determined during operation 504. In certain implementations, the identifier may be inserted into the header of the packet. The packet is then transmitted to the virtual communication platform 106 at operation 508.

Reference is next made to FIGS. 4B and 5B, the latter of which is a flow chart illustrating a method 550 for handling traffic received from the trunking service 108 by the virtual communication platform 106. At operation 552, the virtual communication platform 106 receives a packet, such as the packet generated in operation 504 described above in the context of FIGS. 2A and 3A, from the virtual communication platform 106.

As previously noted, the packets generated and transmitted from the trunking service 108 to the virtual communication platform 106 may generally include a data representation of the signal received by the trunking service 108 as well as an identifier. Accordingly, at operation 554, the virtual communication platform performs a lookup or similar operation using the identifier to determine a location associated with the destination for the signal received by the trunking service 108. For example, the virtual communication platform 106 may perform a lookup using the identifier in order to retrieve a public Internet protocol (IP) address, a combination of a VPN identifier and a private IP address, or a similar location corresponding to one of the client devices 112-118, 120-126.

At operation 556, the virtual communication generates a second packet including the data of the packet received from the trunking service 108 as well as the location obtained during operation 554. The process of generating the second packet may include one of generating a new packet including each of the data and the location or may include replacing the identifier of the packet received from the trunking service 108 or otherwise inserting the location into the packet received from the trunking service 108. Following generation of the second packet, the virtual communication platform 106 transmits the second packet to the appropriate customer network based on the location information.
